A construction assembly for installing a roller blind or the like comprising two parallel guiding sets spaced at a predetermined distance, between which at the least a roller blind can be slid in a guided manner, the at the least roller blind being arranged in the upper part of the two guiding sets.

This construction assembly comprises an internally hollow outer profile that can be fastened to a vertical surface, an internally hollow inner profile that is arranged in the interior of the outer profile, the inner profile having dimensions such that it is insertable into a housing defined by the outer profile by means of a snap fit, and a retaining element configured to retain a longitudinal edge of the roller blind arranged longitudinally along the inner profile.

It is allowed for adjusting the degree of inclination of the two sides of the guiding sets, in case there are irregularities on the surface of the wall on which the assembly is to be installed, by means of a construction arrangement that is relatively easy to carry out and install.

Door with a door leaf which, starting from a closed position, can be wound up to form a multi-layer winding in the course of an opening movement and has a plurality of slats which customarily extend horizontally with their longitudinal axes approximately perpendicular to the direction of the opening movement, and with a guide arrangement for guiding the opening movement comprising preferably helically shaped guide rails in the region of the lateral edges of the slats in planes extending approximately perpendicularly to the longitudinal axes of said slats, and guide elements mounted on lateral edges of the slat which leads during the opening movement can be introduced into the radially outermost windings of said guide rails, wherein the guide elements (42) are fastened to the lateral edges of the leading slat (40) via pivot levers (50) on the leading slat and are mounted on the slat so as to be pivotable with respect to pivot axes extending parallel to the longitudinal axis of the slat.

Sentry systems and methods of installation. The method comprising the following steps. First, the cassette is attached to cassette box and a plurality of holes are drilled in cassette box for attachment to wall by using a plurality of fasteners. Support angles are attached to cassette box, the support angles have preinstalled roller tube end brackets. One end of the roller tube end bracket is attached to idle gudgeon. Other end of the roller tube end bracket is attached to motor. An idle gudgeon is installed to one end of roller tube. Roller tube is attached to roller tube end bracket. Roller tube is pushed towards idle gudgeon to collapse idle bearing. Other end of the roller tube is allowed to spring forward into the roller tube end bracket having motor. Motor retaining clips are installed to retain the motor. Side rails are installed at ends of the cassette box.

A roll-up door including a flexible curtain having a front surface, a back surface, a first end coupled to a shaft, a second end opposite the first end, and first and second side edges extending between the first end and the second end, the flexible curtain being moveable between a retracted position wherein the flexible curtain is coiled around the shaft and a deployed position wherein the flexible curtain is uncoiled from the shaft. A first retention band is mounted along at least a portion of the first side edge of the flexible curtain, the first retention band including an inner surface at least partially facing towards the flexible curtain, an outer surface opposite the inner surface, a fixed edge attached to the flexible curtain generally parallel to the first side edge, and a free edge opposite the fixed edge and movable relative to the fixed edge.

A method for heating a door guide area includes: channeling a flow of heated air in a longitudinal first direction in a first conduit; channeling the flow of heated air in a longitudinal second direction different than the first direction in a second conduit; providing heated air to the second and first conduits by routing the heated air directly from a heater laterally across the first conduit to the second conduit; transferring heat from the flow of heated air in the second conduit to a heated space outside of the first and second conduits; and configuring a side portion of a roll-up door to be in the heated space when the roll-up door is in a closed position.

The present invention relates to a gate with a gate panel, comprising several gate panel sections which are hingedly coupled to each other by way of hinges, where a hinge comprises two hinge panels of adjacent gate panel sections, at least one elongate drive means which is connected to at least one gate panel section, and at least one guide means which is suitable to guide the gate panel during its motion. In order to optimize the gate with regard to its installation space, in particular in the width and depth direction, and to ensure simple and inexpensive yet at the same time still reliable operation of the gate, it is proposed to arrange the elongated drive means at least in sections received in the gate panel section.

The invention is a track system for a retractable wall. The track system includes rigid outer guide tracks and flexible inner track inserts that are connected to the guide tracks by means of flanges located on both. The flexible inserts include a channel that engages with a side edge of a retractable wall, holding the wall in place. The flexible nature of the track inserts allows the inserts to bend, which in turn allows the retractable wall to flex when force is exerted on the retractable wall without breaking the tracks or tearing the wall. When excessive force is applied, the channel of the flexible insert, the walls of which are thicker than the rest of the flexible insert, bend open, so that the side edge of the retractable wall disengages from the channel by means of an opening in the channel.

The invention relates to a door opening and closing structure including a door plate, a transverse bar, a zipper and a pulling string. When a tension is applied on the pulling string and the tension is greater than a gravity of the transverse bar and at least a portion of the door plate, and the at least a portion of the door plate is driven by the transverse bar to move along the extension direction to form an opening. When the tension is less than the gravity of the transverse bar and the at least a portion of the door plate, the door plate is driven by the transverse bar to move along the gravity direction to reduce the opening.

A perimeter light blockout system for minimizing light leakage between light gaps such as, for example, between the sides of a covering (e.g., shade) of an architectural-structure covering and the interior side surfaces of a window frame, or between the covering and the outer surface of an interior wall is disclosed. The perimeter light blockout system including a light blocking device and a mounting element for coupling the light blocking device to the interior side surface of the window frame, or the outer surface of the interior wall. The light blocking device may include rear and front channel members. The mounting element may be a mounting extrusion. Alternatively, the mounting element may be a spring clip. In use, the light blocking device may be adapted and configured so as not to contact the covering as the covering moves between extended and retracted positions. The mounting element may include a degree of adjustment so that the light blocking device may be aligned with an out-of-skew window frame.

A rollable device for occluding an opening of a residential building, includes a frame mounted in the opening and provided with at least two lateral guiding slides with a U-shaped cross-section, in order to define a general closure plane, and a set of transverse slats hinging relative to each other in pairs by the respective longitudinal edges thereof, the slats sliding within the two slides between a first inactive raised position in which the slats are wound about an upper transverse axis and a second active lowered position in which the slats are unwound and form an apron for closing the opening. The cross-section of the lateral slides is greater than the thickness of the slats and in the second active lowered position, the slats adopt a vertical accordion configuration in the lateral slides and form, relative to each other in pairs, an angle other than 180?.
